[Python] How to export project texture with my own preset?

I just figure out how could we do that with the following script below

import substance_painter as sp
#List all of the shelf exist in the current project
exist_shelves = sp.resource.Shelves.all()
#After the result printed in the console
#[Shelf(_name='stater_assets'), Shelf(_name='your_assets')]
#After have the result, we have to check if that shelf available to import resource
sp.resource.Shelf.('shelf_name_from_exist_shelves').can_import_resources()
#If the shelf return 'True' value, we move on the next step and use that shelf name as the 'shelf_name_from_exist_shelves' below
#Define the usage of the resoure you going to import as the export-preset
sp.resource.Shelf('shelf_name_from_exist_shelves').import_resource(file_path, sp.resource.Usage.EXPORT)

#Define export preset
export_preset = sp.resource.ResourceID(context='shelf_name_from_exist_shelves', name = 'your_export_preset_name')

export_config = {
    "exportShaderParams": False,
    "exportPath": "your:\export\Path\Here",
    "defaultExportPreset" : export_preset.url(),
    "exportList": [
        {
            "rootPath": "01_Head"
        },
        {
            "rootPath": "02_Body"
        },
        {
            "rootPath": "03_Base"
        }],
    "exportParameters": [
        {
            "parameters": {
                "fileFormat" : "png",
                "bitDepth" : "8",
                "dithering": True,
                "paddingAlgorithm": "infinite"
            }
        }]
    }
